Failing Fuel Check?

[art leong]

I've run C12 since I started running the Neon. It has passed every time they never told me I was close.
The winter before last I had about 3 gallons the the 5 gallon cell and about 3 gallons in a blue metal can I bought the fuel in October. It sat in my garage for 4 months when I took the car to Bradenton I figured it would never pass so I brought a fresh 5 gallons with me.
Only got one run in the test and tune. So on Friday I drove up to fuel check to see if it might still be good (I had 5 gallons of the stuff total) It passed with flying colors. When I took the can up it also passed right in the middle.
The only time I had a potential problem was with the fuel they sold me this year at Gainesville points meet, I went to Atlanta the following week and was told it wouldn't pass, so I pumped it out. put it 5 gallons of fresh fuel. Didn't wash anything or clean the filters.
And it passed without problems. And they checked it 3 times because of the record.
